SEPARATING- MECHANISM.

Application filed July V28, 1923. Serial No. 654,435.

To all whom t may concern.

Be it known that I, FRED I-I. MASON, citizen of United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certainl new and useful Improvements in Separating Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in separating mechanism and more especially to mechanisms adapted to separate coal from slate, rock, bone and other extraneous matter.

An object of the invention is to provide a suitable separating mechanism comprising stepped plates spaced apart and having the interval between the plates partially filled with a plurality of resiliently mounted slidable rods, which are adapted to be vibrated by the reciprocation of the shaking screen to which the entire apparatus is attached.

Another object of the invention is to provide a separa-ting mechanism for attachment to a shaking screen commonly employed in breaker houses for use in separating slate, rock, bone and other extraneous matter from the coal, said mechanism to be provided with a plurality of interchangeable resiliently mounted rods which partially lill up the spaces between the stepped plates of the mechanism, and are adapted to be vibrated by the reciprocation of the shaking screen.

Other objects will appear as the description proceeds.

In the accompanying drawings which form a part of my application,

Figure 1 is a side elevation of my improved mechanism showing the resilient mountings for the several rods.

Figure 2 is a longitudinal sectional view taken through the apparatus.

Figure 3 is a sectional View taken on the line 3 3 of Figure 1, and

Figure 4 is a detailed view of one of the locking bolts for holding the resilient supporting member in position.

Like characters of reference are used throughout the following specification and the accompanying drawings designate corresponding parts.

My improved separating mechanism is adapted to be attached to shaking screen l of usual construction which is used in breaker houses for separating extraneous matter from coal as it 1s brought from the Amines. The separating mechanism is composed of spaced side members 2l which have notches 6 are a plurality of locking bolts "1'` which are provided with undercut nuts 8, which are adapted to receive and securely hold one end of the resilient supporting rods or members 9. These members 9 have a spiral formation 10 adjacent their central portions, and are angularly bent as at 11 and are adapted to extend through the supporting rods l2.

These resilient supportings rods or members 9 will be positioned on the outside of each of the side members 2 and are adapted to support the opposite ends of the rods 12 in such a manner that when the shaking screen l, is reciprocating, rods 12 will be caused to vibrate.

It will be understood that the coal as it is v brought from the mines is fed on to the shaking screen, after which it passes on to the separating mechanism and the thin pieces 0f slate, rock, bone, or other extraneous matter will pass above or below the rods 12 and between the adjacent ends of the bottom plates 3 there to be collected and carried to the dump pile. The cleaned coal will pass over the bottom plates and be collected in any suitable manner as is the usual procedure.

Many minor changes 'in detail of description may be resorted to without departure from the spirit of the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters .Patent of the United States is:

l. In a separating mechanism spaced side members, plates extending between said side members having their adjacent edges spaced apart and resiliently mounted rods interposed between the adjacent spaced edges of said plates.

2. In a separating mechanism spaced side members, angularly disposed plates extending between said side members and having their adjacent members spaced apart and resiliently mounted rods positioned between the adjacent edges ot' said plates.

3. A separating mechanism in combination with a shakin g screen comprising` spaced side members spaced bottom plates connecting said side members, said side members being provided with a plurality of spaced slots and a plurality ot resiliently mounted rods adapted to sliding,` in said slots.

il. A separating mechanism con'lprising spaced side members and plurality of plates connecting the same and being spaced apart one from the other and a plurality of interchangeable resiliently mounted rods positioned between the adjacent ends of said plates.

5. A separating mechanism comprising spaced side members and plurality of angularly disposed spaced bottom plates connecting said side members, said side members being provided with a plurality of angularly disposed slots between the adjacent ends of said bottom plates, said slots eX- tending in substantially the same plane with said bottom plates, and a plurality ot rods movably positioned within said slots and a plurality of interchangeable resilient supporting` means adapted to be supported to opposite ends of said rods.

In testimony whereof I affix my signature.

FRED H. MASON.
